lVhen the pr` lurc described is applied through the screw and lcvcr 25, it is preferabl)v al a poinl on a limx beloven the pin and thc point. ol' cnraoeincnl o" the needle or stylus with ihc vibrating reed. This reacis through iin lever l5 ro pull oulivarlilv, that is. toward the adjueiing sci-civ in` Fig. 2 dravvinir correspondiugly on the diaphragm, and without ripping the sound box.

It is to be understood that various- :nodi-- iications ol our dcvimf univ be employed io tension or alter 'the normal plane oi' the diaphragm oi various kinds o l sound producing` mechanisms. ll adiuslin; dns screw while operating with .suitable current such as the output of a radio receiviinY apparatus, one may judge when the best results are obtained.
